| Abstract: | The angle estimation of the target under the condition of chaff centroid jamming is studied based on the monopulse radar system. The sum and difference signal model based on dual polarization is presented, and the statistical characteristics of target and chaff jamming are analyzed. Based on this, a method for estimating the angle of the target based on polarization monopulse radar is proposed, and the main workflow of estimation is given in detail. The simulation experiments on the performance of angle estimation are carried out under the conditions of various values of subpulses, signal to interference ratio (SIR), signal to noise ratio (SNR), and chaff clouds' distribution, etc., and the estimation performance is compared with the other methods. |
